MAX6934 Datasheet Serial-interfaced Vfd Tube Drivers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: .. 19-3224; Rev 0; 1/04 27-, 28-, and 32-Output, 76V, Serial-Interfaced VFD Tube.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX6922/MAX6932/MAX6933/MAX6934 multi-output, 76V, vacuum-fluorescent display (VFD) tube drivers that interface a VFD tube to a microcontroller or a VFD controller, such as the MAX6850–MAX6853.

The MAX6922/MAX6934 have 32 outputs, while the MAX6932 has 27 outputs, and the MAX6933 has 28 outputs.

All devices are also suitable for driving tele relays.
